VALVE-MOTION BEARER GROSSTIEFOR LOCOMOTIVES.

Application filed December 20, 1926. Serial 155,933.

This invention relates to certain improveside of the locomotive to the other, and also supports the rockers of the valve mechanism.

The object of the invention is to make the bearer cross-tie in asingle casting, preferably of steel, and to provide means for supporting the bracket bearings on which are mounted the parts of the valve mechanism.

In the accompanying drawings Fig. l is a side view of my improved valve motion bearer cross-tie for locomotives;

Fig. 2 is a plan view;

Fig. 3 is an end view;

Fig. 4 is a sectional view on the line air-4, Fig. 1; and

Fig. 5 is a perspective view showing the parts of the valve mechanism assembled on the cross-tie.

The bearer cross-tie is made in a single casting, and has a central portion 1 pro vided with feet 2 which rest upon the frames a--a of the locomotive shown by dotted lines in Fig. 1. i

Depending from these feet are deep flanges 3, which are secured to the sidesof the frames by bolts or other fastenings.

Projecting from each end of the body portion of the cross-tie are brackets 4 which overhang the framesand have plates 5 at their lower ends to which the guides 7)b for the cross-heads of the side cylinders are secured, the opposite ends of the guides being secured to a guide bearer cross-tie which is located between the ends of the cylinders and the valve motion bearer cross-tie.

At the end of each bracket are surfaces .6 i in which are bolt-holes The brackets 0 carrying the links of the valve motion are secured by bolts to the surfaces 6. At the top of one of. the brackets is an elongated platform 7, whileon the opposite bracket is a narrower platform 8. The bearingbrackets cl-dfor the reverse shaft are secured to these platforms.

At one side of the bearer cross-tie are surfaces 9 and 10, on which are mounted the bearings e-e for the low-pressure linkshaft. The cross-tie has a web which is reinforced by top and bottom flanges 11 and 12, and is perforated at 13 in order to lighten the structure, while surrounding these perforations are strengthening flanges;

At the front of the cross-tie is an upwardly projecting centrally located plate 14, having surfaces 15 to receive the supports for the brake cylinder, and at the rear is a centrally located flange 16 to which a waist sheet is secured bybolts or other fastenings.

By this construction the cross-shafts and links, and their connecting mechanism, can be attached to the cross-tie before it is placed. in position on the frame of the locomotive thus making assembly accurate and rapid.

I claim I i 1. A valve motion bearer cross-tie for locomotives, made in a single casting and having feet which rest upon the frame of the locomotive; overhanging brackets at each side shaped to receive the bearings for the'links of the valve mechanism; a plate at one side to receive the supports for a brake cylinder and having a flange at the opposite side to which a waist sheet is secured; platforms at its upper edge on which. are mounted the bearings for the reverse shaft; and surfaces at the sides to which the bearings for the low-pressure link-shafts are secured.

2. A valve motion bearer cross-tie for locomotives, made in a single casting and having feet which rest upon the frame of the locomotive; overhanging brackets at each side shaped to receive the bearings for the links of the valve mechanism; platforms at its upper edge on which are mounted the bearings for the reverse shaft; and surfaces at the sides to which the bearings for the low-pressure link-shafts are secured.
